1.attempt to start chromium browser from menu (or from command line)
2.
3.
  
Actual results:
chromium does not start

Expected results:


Additional info:

watching tail -f /var/log/messages i could see this kind of message:

Oct 12 18:13:15 otp-cpanceac-l1 kernel: [ 6026.209887] type=1400
audit(1318432395.873:7): avc:  denied  { execmod } for  pid=4427
comm="chromium-browse" path="/usr/lib/chromium-browser/chromium-browser"
dev=sda5 ino=3016262
scontext=unconfined_u:unconfined_r:chrome_sandbox_t:s0-s0:c0.c1023
tcontext=system_u:object_r:execmem_exec_t:s0 tclass=file

abrt gui doesn't show up reporting the application was blocked but i've noticed that

setenforce 0

allows chromium to start. if it's started, it works fine even after

setenforce 1

On one system i've fixed it in two steps:

first

sealert -l eb8e8127-2771-4dfc-9918-d0c158cbe109
semanage fcontext -a -t textrel_shlib_t '/usr/lib/chromium-browser/chromium-browser'
restorecon -v '/usr/lib/chromium-browser/chromium-browser'

then

grep chrome-sandbox /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp
